Clavicular fracture is one of the most common fractures, accounting for about 4 % of all fractures. Midshaft fractures account for approximately 80%. Traditionally, midshaft fractures have been thought to have a good prognosis even when substantially displaced, and most have been treated nonoperatively with a sling or a figure of eight bandage. Early studies by Neer and Rowe in the 60´s demonstrated a very low non-union rate, with av prevalence of 4 in a series of 566 patients, and 3 nonunions in 2235 in another. On this basis, the general view has been that the vast majority of even severely displaced midshaft fractures healed uneventfully, with a very low nonunion rate and a good functional result. Operative results reported on the other hand bad results, especially concerning the risk of infection. Recent studies, however, conclude differently, and suggest the outcomes of displaced fractures might not be as favourable as once thought. Hill showed in a series of 52 completely displaced midclavicular fractures a nonunion rate of 15% (8 of 52 patients) and 31% (16 of 52) of patients were not satisfied with the end result. This correlated with a shortening of more than 2 cm. In a prospective study of 222 patients by Nowak, 42% (93 of 222) were found to have persisting symptoms after 6 months wheras 15% were found to have nonunion. These symptoms seem to persist even after 9 - 10 years reporting 29 % of 208 patients having pain during activity and 9% pain at rest. 46% did not consider themselves fully recovered.
